We were just up at Breezy Point. Nothing, it is a desert as far as car charging goes, however 110 outlets are plentiful
If you have access to a 110 outlet and are up for the weekend that should be plenty.

Where is your start point? The furthest North charging spot I know of would be the goodwill in Blaine. They have a free J1772. You would also be welcome to stop by my house to top off on our NEMA 14-50 (also in Blaine).
I would recommend the 169 route north through garrison.

Grand Casino Mille Lacs, it is rumored, is putting some chargers in, in the near future.

I've looked into driving to Fargo and back, and spotted some RV parks in Saint Cloud that might work for that drive, but that's about as close as I've gotten. It's 115 miles to Brainerd. You can make it, I made it to Duluth and back (wait for my blog!) and in retrospect didn't need a range charge. I drove to Mora, MN last weekend on Hwy 169 and back with 30+ miles left of range (charged up to 190 miles of range), and that was with 5 people in my 60kWh. I averaged 300 wh/mi up and 260 wh/mi back.
I had a 110v outlet in my garage for weeks before I got around to installing my NEMA 14-50. Drive up with a standard charge of 180 miles. Drive perhaps 120 miles and you're down to 60 miles. Average 3 mi/hr of charging, leave Friday at 6:00pm and get there by 8:00pm, then plug in right away. by 8:00am you will have 35 miles, back up to 95 miles. Even if you didn't plug it in at all after 8:00am on Saturday until night time, you could still get back another 35 miles Saturday night, back up to 125 miles 8:00am Sunday morning. A few places there may have an EV charging 110v outlet, so if you went to a restaurant for dinner, pick one near a Kwik Trip, Walgreens, and maybe Country Inns and Suites will have a 110v for a block heater plug.
If you're concerned about range during your weekend, you can go up with a max charge of 208 miles. Drive 55mph, plan everywhere you will drive beyond up and back, and find a charging spot where you can if you leave your home base.
You have a lot of options and you can make the trip, just plan for it.

I'm headed to a camping trip into Wisconsin in a couple weeks, it takes a lot of planning!

I reached out to Madden's on Gull Lake to see if they had any options. They worked really hard to set aside a parking space near my room that was in reach of a 110V outlet via an extension chord. Because of Tesla's admonitions against using extension chords, however, I played it safe and brought the BMW X3.

But I definitely appreciate they effort they went through to accommodate me with the infrastructure they have and it would likely fit anyone less skittish about extension chords.

I had provided them with some recommendations on setting up a charging station for future stuff. They mentioned that my inquiry was the second of the season, and it's something they are looking into.
